4 Claims. (o1. 72-115) This invention relates to metal studs used in the construction of walls, partitions and similar structures made of composition sheets or blocks such as plaster boards and the like.

In theerection of walls or partitions which are constructed of plaster boards joined together by fastening devices and wooden studs, and then having plaster applied thereto, there has been considerable difficulty encountered by reason of the plaster cracking at the points in the wall 'where the wooden studs are located due to the shrinkage of the wood. The erection of such walls also entails considerable time and carpentry work, and the wall is not entirely fire-proof because of the wooden studs employed in the'construction. Furthermore it has been difficult to properly reinforce such a wall or partition.

It is the purpose and object of my present invention to provide an improved stud of metal con.- ruction for use in theerection of such type of walls or partitions which will not only afford means for reinforcing the sheets of plaster boards arranged to form the wall or partition, but will also permit the construction of the wall more rapidly and without the necessity of carpentry work and at a less cost than has heretofore been possible.

A further object of the invention is to provide a metal stud for Wall or partition construction which will not only add to the strength of the wall when erected, but will also render said structure more fireproof.

A further object of the invention is to provide a metal stud for wall or partition construction which will permit a reinforced wall or partition to be erected of a lesser thickness than ordinary walls or partitions and thus conserve considerable space in'a building or other structure where the partition is used.

A further object of the invention is to provide a stud for wall or partition construction which will eliminate the possibility of the cracking of the plaster at the points where the stud is located in the wall.

Further objects of the invention will appear hereinafter and I attain these objects by the con- Figure 3 is a front elevational view of a portion of a metal stud made in accordance with my invention;

Fig.4 is a side elevational view'of the portion of stud shown in Figure 3;. I

Fig. 5is a front elevational view of a portion of a modified construction of stud made in accordance with my invention;

1 Fig. 6 is a side elevation of the portion of stud shown in Figure 5; I

Fig. '7 is a sectional view of Figure 3; and Fig. 8 is a sectional view of Figure 4.

The same reference characters indicate simi-' lar parts throughout the several views.

Referringto Figure l of the drawings, 1 have shown a portion of a partition built with the plaster boards 1 to 12 and fastened together at their end edges by means of the fastening devices. 13 and separated from each other at their side edges by the inetalstuds 14 of my invention. The'portion of the partition built up by the plaster'boards and the metal studs is shown as reinforced by the metal rods 15' which are adapted to pass through and be supported'by the metal studs as will be hereinafter more fully explained; -The metal studs are shown as secured to the base or floor section 16 and the ceiling 17 at 18, 18, 13 and at 19, 19, 19.

The studs 14 of my invention are made of any suitable metal and are formed in strips of the desired length for the height of the wall or partition to be constructed and so that the ends thereof at 18 and 19 may be bent and nailed to or otherwise secured to the floor or ceiling of the room or space to be partitioned. In the preferred form of stud as shown in Figure 3, the metalstrip is made of greater width than the plaster board used to form the wall or partition and is formed with side portions 20 and 21 bent up at right angles to the plane of the strip. The ,95 stud shown in Figure 5 is made without the bent up side portions but in all other respects is similar to the stud illustrated in Figure 3.

Throughout the strip at staggered intervals are the holes or openings 22 which are punched out of the strip as clearly shown in the drawings (Figs. 4, 6, 7, and 8). These holes or openings are shown as elongated ovals but any other shaped hole such as a round opening would be within the scope of my invention and while the elongated oval shape as shown has been found to be preferable in carrying out my invention, 1 do notwish to be restricted to the particular shape of opening shown. It will be noted that the holes 22 are positioned in the metal strip forming the stud so as to have a portion of the hole approximately in the line of the center of the strip.

In the construction of a wall or partition of plaster boards wherein my improved metal stud is used the plaster boards are erected by connect.- ing them together by suitable fastening devices such as are shown at 13 in Figure 1. In the particular construction of fastening devices shown in Figure 1, the ends of the plaster boards are held in position with each other in a uniform spaced relation thus leaving a space for the reception of plaster, mortar, cement or other binding material. The metal studs of my invention are positioned so that the side edges of the plaster boards abut against the same at the approximate center of the stud and the ends of said studs are then fastened to the floor and ceiling in any suitable manner. The rods 15 are then inserted through the holes 22 of the studs on both sides of the plaster boards so that they connect up with the studs with the plaster boards therebetween. As many of these rods may be used as is deemed necessary to adequately reinforce and strengthen the wall built up from the plaster boards. In view of the elongated or oval shape of the holes 22 in the studs the rods 15 when inserted therein nestle in the lower part of the hole and in view of the fact that the lower part of the holes are nearest the faces of the plaster boards the rods bind themselves against the plaster board and present a rigid reinforcement therefor.

After the wall is built up with the plaster boards, connecting clips, metal studs and reinforcing rods, plaster is applied thereto to the desired thickness and so that it completely covers the edges of the metal stud and so that there is formed a plastered partition or wall of unbroken continuity. Due to the punched out holes in the metal strip of the stud the plaster enters said holes and sets therein so as to further bind the studs to the rest of the wall structure.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

1. In a plaster board wall construction, a stud for supporting plaster boards in their assembled relation, consisting of a metallic strip extending the height of the wall to be erected and formed with bent up side portions and having a plurality of slots therein positioned in staggered relation adjacent the center line of said strips, and rods on opposite sides of said plaster boards adjustably held in the slots.

2. In a plaster board wall construction, a stud for supporting plaster boards in their assembled relation, consisting of a metallic strip extending the height of the wall to be erected, and formed of a width greater than the thickness of the plaster boards, and having a plurality of oval slots therein positioned in staggered relation with each other adjacent the center line of said strip, and reinforcing rods adjustably clamped by said slots on-opposite sides of said plaster boards.

3. In a plaster board wall construction, a stud for supporting'plaster boards in their assembled relation, consisting of a metal strip extending the height of the wall to be erected and having bent up side edges, said metallic; strip being of a greater width than the plaster boards and having a plurality of elongated slots therein and extending in staggered relation throughoutthe length of said strip and positioned so that the lower portions of the elongated holes are in a line with the center line of the strip and rods in said slots on opposite sides of the plaster boards.

4. In a plaster board wall construction, a metallic stud for supporting plaster boards in their assembled relation, said stud comprising a flat metallic strip having its edges bent to form right angle side portions, and having openings formed throughout its length and reinforcing rods therein on opposite sides of said plaster boards, said openings in said strip being elongated in formation and arranged in staggered relation with each other in such manner that the lower portion of said openings lie approximately along the center line of said strip, said strip being of greater width than the thickness of the plaster boards forming the wall construction.
